Eighteen-year-old Cass Issac doesn’t believe in sticking around. She's had to move a lot due to her dads' house-flipping business—always a different school, always a new friend group. She’s learned there’s no need for drawn-out-goodbyes with people you'll lose touch with anyway. Which makes Grad Nite at Disneyland the perfect way to finish up high school, and have a magical last night with her best friend, Bryony–before she leaves once again. But amid the roller coaster rides and Cars Land dance party, the night turns into one big disaster.

Andie has a plan. And she always sticks to her plan. Future? A top-tier medical school. Dad? Avoid him as much as possible (which isn't that hard considering he's a congressman and he's never around). Friends? Palmer, Bri, and Toby - pretty much the most awesome people on the planet. Who needs anyone else? Relationships? No one's worth more than three weeks. So it's no surprise that Andie's got her summer all planned out, too.

They’re barely off the train before they’re dealing with destroyed phones, family drama, and unexpected Pomeranians. Over the next few hours, they’ll have to grapple with old flames, terrible theater, and unhelpful cab drivers. But there are also cute boys to kiss, parties to crash....

In the aftermath of a music festival, she’s stranded at a bus station until morning—the day before she leaves for college. Her phone is dead, she has no cash, and she’s convinced nothing good can come of this night...but then she meets Russell.
